Question

Development of pollen grains before the dehiscence of another

• A. In-situ development
• B. Ex-situ development
• C. Precocious development
• D. In vivo and In vitro development

Answer 1

The correct option is A In-situ development

Anther dehiscence is the final function of the anther that causes the release of pollen grains. In some flowers, development or germination of pollen grains is observed before the dehiscence of anther. This is called as in-situ development. The frequency of germinating pollen grains varies from anther to anther.

Thus, the correct answer is 'In-situ development'.
